Diamond Mining Methods
Two Different Methods are Used to Mine
How often do you think about the diamonds you wear? Where they come from? How
they're mined? What do you know about diamond mining methods?
Natural diamonds, as opposed to synthetic diamonds or fake
diamonds, are mined from the earth. There are currently two methods of
mining diamonds: Pipe Mining and Alluvial
When pipe mining is used, the diamonds are extracted from the earth through
volcanic pipes. As the name suggest, these are not man-made pipes, but natural pipes in the ground. The
ripper shanks are put
into the ground next to the pipes to loosen or fragment the rock, and tunnels are driven into the deepest parts
of the volcanic pipe.
|The current top five diamond mining countries include:
Russia, Australia, Ukraine and Republic of Guinea (West
The diamonds are not sorted out at the mine. Instead, huge rocks that are full of
diamonds are brought out of the mine and moved to a screening plant for separation. To find one small diamond,
often over two hundred tonnes of ore must be mined. Natural diamonds are truly rare.
The Alluvial mining method is done in riverbeds and on beaches. Walls are built to
hold back the water and the sand on the river bank. When diamond mining is done on the beach, the sand is moved
with a bulldozer until it unearths the level of earth where diamonds can be found.
As with pipe mining, the diamonds are not sorted here. Instead, the sand that
contains the diamonds is bulldozed into trucks, and taken to screening plants for
